Hydraulic equipment for clams-
hell (option)
The hydraulic equipment for the clamshell enables the connection
and use of a clamshell.
Installing the clamshell
1 Place the machine on firm and level ground. Position the mach-
ine as required for the clamshell laying flat on the ground.
2 Slowly lower and align the boom, until the fastening bores of
the clamshell are flush with the holes in the boom.
3 Carefully retract the dipper arm.
4 Close the shut-off valve (C) on the dipper arm cylinder.
5 Connect the hydraulic hoses of the clamshell to the hydraulic
couplings (return line (A) and pressure line (B)) on both sides
of the dipper arm.
IMPORTANT! Protect the hydraulic connections against dirt,
because only this will ensure the correct function of hydrau-
lic connections and hydraulic system!
NOTE! Depending on the equipment the hydraulic connec-
tions on the boom can vary from the illustration and the des-
cription.
WARNING!
Safety regulations, operating instructions and maintenance
instructions issued by the clamshell manufacturer must be
strictly observed!
WARNING!
Before removing or connecting hydraulic hoses the engine
must be shut down and the control levers shifted to all
directions, in order to relieve any trapped pressure. It must
be strictly assured that the engine cannot be started after
hydraulic couplings have been opened.
